The heart of the matter in all the controversy over +Williamson's statements to the emotional woman in Mahopac, NY last summer is:
Is the Novus Ordo Mass intrinsically evil like a Black Mass?
Intrinsically evil means "evil in its very essence", an evil you can't possibly escape from due to circuмstances. For example, Abortion, Sodomy, or interfering with nature to prevent conception from occuring. Or any sin, for that matter. You can never sin that some good might come from it, because sin is an infinite offense against God, and intrinsically evil.
A rotten apple isn't intrinsically evil. It's a great food for certain farm animals, or at least the compost pile. Likewise a rusty nail can be sold to the recycling place and melted down to make something useful. A flat tire can be used to make a garden bed or planter. An empty 2-liter bottle can be used to store water. And so forth.
It doesn't matter who you are, where you live, what your circuмstances -- a priest could never permit a person to get out the forceps or saline solution and have an abortion, or commit sodomy, or attend a Black Mass. No matter what your state of mind, subjective opinion, your family's beliefs, your economic situation, etc.
(A woman with life-threatening cancer might undergo chemotherapy which could kill the baby, but this is "double effect" and she isn't willing the death of the baby. She's not "having an abortion", she's undergoing medical treatment, which MIGHT HAPPEN TO kill the baby as an unintended consequence. There's a difference.)
But if the Novus Ordo is truly as evil as a Black Mass, for everyone in all cases, then why don't we all:
A) deny that ANY converts from the Novus Ordo were Catholic
B) require converted satanists/Novus Ordo Catholics to undergo a full catechumen process, formal abjuration of their heresies/satanism, and baptism
C) Require converts from the Novus Ordo to confess how many times they attended the Novus Ordo as part of their "first confession"
D) become sedevacantists (and, like most sedevacantists, become ecclesiavacantists as well), because we're talking about the "Catholic Church" pushing a positively evil BLACK MASS EQUIVALENT on the entire world! The Catholic Church could never do that.
E) get SERIOUSLY vocal (shouting at a minimum, throwing things optional but preferred) with our friends and family members who still attend the Novus Ordo. Forget ignorance, good will, familial relationships, civility, etc.! Would you let a friend go to a Black Mass every Sunday without saying something, and taking serious action? I didn't think so. We should be boycotting them, totally cutting them off, and making a huge deal out of their weekly blasphemous attendance at a Black Mass.
